Ichneumonid wasps of the Polysphincta genus-group (Polysphinctini sensu Townes hereafter "polysphinctine wasps") are exclusively koinobiont ectoparasitoids of spiders (Fitton et al. 1987; Gauld 2006). Since the first report of a spider's behavior being manipulated by a polysphinctine wasp (Eberhard 2000), several studies have since focused on unravelling the mechanisms and evolution of this association (e.g. Gonzaga & Sobczak 2007; Matsumoto 2009; Sobczak et al. 2009; Eberhard 2010; Gonzaga & Sobczak 2011; Korenko & Pekár 2011; Korenko et al. 2013; Sobczak et al. 2014; Takasuka et al. 2015).

Some ichneumonid wasps of the Polysphincta group of genera (Hymenoptera: Ichneumonidae: Pimplinae) induce behavioral modifications in their host spiders during a specific moment of their development, resulting in the construction of webs that differ in several aspects from those constructed by unparasitized individuals. In this study, we describe the parasitoid wasp Hymenoepimecis pinheirensis sp. n.

All species included in the Polysphincta genus-group develop as ectophagous parasitoids of active spiders, killing their hosts prior to pupation. However, little information regarding natural history and ovipositing behavior of most species are available. In this study we inspected 85 webs of Araneus omnicolor to evaluate the frequency of parasitism and host size preferences of the wasp Hymenoepimecis sp.
